After acquiring Andrew McCutchen from the Pittsburgh Pirates and signing free agent Austin Jackson, the Giants indicated they weren’t finished adding to an already crowded outfield.

On Monday afternoon, general manager Bobby Evans kept his word.

Former Giants outfielder Gregor Blanco has inked a Minor League contract with the organization, returning to a team he spent five seasons with earlier in his career.

The 34-year-old Blanco is a plus-defender who could have an opportunity to win a platoon job in center field during Spring Training. San Francisco doesn’t expect Jackson to serve as an everyday outfielder, and top center field prospect Steven Duggar may not be ready to play at the Major League level until later in the year.

With uncertainty in the middle of the outfield and a desire to keep their payroll under the $197 million luxury tax threshold, the Giants signed Blanco to a Minor League contract to provide the team with a left-handed bat to potentially pair with Jackson, a right-hander.

Blanco won two World Series with the Giants, one in his first season with the franchise in 2012 and another in 2014. Still, his greatest contribution came during a regular season game, when he soared into the right center field alleyway to make a diving grab that preserved Matt Cain’s perfect game on June 13, 2012.

Blanco’s highlight-reel snag of a Jordan Schafer flyball to lead off the top of the seventh inning was the defining defensive play in the only perfect game in Giants history.

After playing in 90 games and hitting .246 with an on-base percentage of .337 for the Arizona Diamondbacks last season, Blanco hit the free agent market this offseason and remained unsigned until Monday.

The Giants were reportedly tied to other free agent center field candidates like Jarrod Dyson, Jon Jay and Cameron Maybin, but the franchise was able to add Blanco on a Minor League deal while other center fielders would have commanded more significant salaries.

Following a trade of Denard Span to the Tampa Bays in the Evan Longoria deal in December, the Giants have now added three players —Jackson, McCutchen and Blanco— with experience playing center field to a team looking to shore up its outfield defense. Span ranked near the bottom of all Major League outfielders in Outs Above Average (OAA) last season, which made upgrading the team’s center field defense a top priority for Evans and vice president of baseball operations Brian Sabean.

Blanco will enter a competition for outfield playing time that also includes Jarrett Parker, Austin Slater, Gorkys Hernandez and Mac Williamson.

With Hunter Pence expected to start the season in left, McCutchen penciled in to play right and Jackson capable of starting in center or adding depth, Blanco’s speed, left-handedness and range in the outfield are qualities that could help him stand out in a crowded battle this spring.

The nine-year Major League veteran may not enter camp with great odds of making the 25-man roster, but Blanco is a favorite of manager Bruce Bochy and he could wind up helping the Giants at some point in 2018.
